For each arch in tools/perf/arch, grab a copy of errno.h.
This is a pre-req to generate an architecture specific mapping of
errno numbers to their names. This errno mapping can be used by
perf trace to support cross-architecture trace reports and to get
rid of the audit-libs dependency.

This is a pre-req to generate an architecture specific mapping of
errno numbers to their names. This errno mapping can be used by
perf trace to support cross-architecture trace reports and to
get rid of the audit-libs dependency.

Introduce a script that generates a mapping of errno numbers to
their names for each architecture that is supported by perf (i.e.
has a subdirectory in tools/perf/arch/).
The errno mapping is generated as part of the trace beautifiers
and can be used by including the trace/beauty/arch_errno_names.c
file. Then, use arch_syscalls__strerrno() to look up an errno value
to obtain the errno name (e.g. ENOENT) for a particular architecture.

Replace the errno_to_name() from the audit-libs with the newly
introduced arch_syscalls__strerrno() function.
With this change:
1. With replacing errno_to_name() from audit-libs, perf trace
does no longer require audit-lib interfaces.
2. In addition to 1, the audit-libs dependency can be removed
for architectures that support syscall tables in perf.
This is achieved in a follow-up commit.
3. With the architecture specific errno number/name mapping,
perf trace reports can work across architectures.

So, I need this extra patch to really stop linking against
audit-libs-devel (aka libaudit), which I merged with this 5/5 patch and
have now in my tree, thanks for your work! Now we can get on with this
and, for instance, get rid of those strcmp() and big switch statements,
which I think that could be just an array plus a helper to see if it is
in its bounds, etc, i.e. use an strarray, look at
tools/perf/trace/beauty/beauty.h:
struct strarray {
int offset;
int nr_entries;
const char **entries;
};
#define DEFINE_STRARRAY(array) struct strarray strarray__##array = { \
.nr_entries = ARRAY_SIZE(array), \
.entries = array, \
}
#define DEFINE_STRARRAY_OFFSET(array, off) struct strarray strarray__##array = { \
.offset = off, \
.nr_entries = ARRAY_SIZE(array), \
.entries = array, \
}
size_t strarray__scnprintf(struct strarray *sa, char *bf, size_t size, const char *intfmt, int val);
tools/perf/trace/beauty/ has lots of uses for it.

I haven't tested this but are you sure that we can do cross-arch perf-trace
after this patch set?
Why I'm curious is because, we embed arch specific syscall table in the perf
binary at compile time:
$ cat tools/perf/util/syscalltbl.c
#if defined(__x86_64__)
#include <asm/syscalls_64.c>
const int syscalltbl_native_max_id = SYSCALLTBL_x86_64_MAX_ID;
static const char **syscalltbl_native = syscalltbl_x86_64;
#elif defined(__s390x__)
#include <asm/syscalls_64.c>
const int syscalltbl_native_max_id = SYSCALLTBL_S390_64_MAX_ID;
static const char **syscalltbl_native = syscalltbl_s390_64;
#endif
If we don't have, let's say, s390 syscall table in perf compiled on x86 machine,
we won't be able to do perf-trace across architecture. Right ?
Please let me know if I'm missing anything.
Thanks,
Ravi
P.S.: Seems I can remove libaudit dependency for syscalls on PowerPC as well.
Will prepare patches for that very soon.

Right.

You are not, we need to start testing running 'perf trace record' for
some workloads on a, say, PowerPC machine, run perf trace -i on that
file to do the beautification, copy this formatted output file + its
perf.data file, copy that to x86_64 or s/390 and try to get the same
